A heifer is a dairy cow that has not yet borne a calf, but soon will. It can produce four gallons of milk a day—enough for a family to drink, share with neighbors and sell for cash.

By adding protein to their diets, milk helps make sick, undernourished children healthy. The sale of surplus milk earns money for school fees, medicine, clothing and home improvements.

Each family that receives a heifer passes on the gift of the first female calf to another family. Would you or your class like to help people around the world achieve self-sufficiency?
